A numeric casting discrepancy in sdla_xfer in Linux kernel 2.6.x up to 2.6.5 and 2.4 up to 2.4.29-rc1 allows local users to read portions of kernel memory via a large len argument, which is received as an int but cast to a short, which prevents a read loop from filling a buffer.

Multiple integer overflows in Sbus PROM driver (drivers/sbus/char/openprom.c) for the Linux kernel 2.4.x up to 2.4.27, 2.6.x up to 2.6.7, and possibly later versions, allow local users to execute arbitrary code by specifying (1) a small buffer size to the copyin_string function or (2) a negative buffer size to the copyin function.

Certain USB drivers in the Linux 2.4 kernel use the copy_to_user function on uninitialized structures, which could allow local users to obtain sensitive information by reading memory that was not cleared from previous usage.

Multiple race conditions in the terminal layer in Linux 2.4.x, and 2.6.x before 2.6.9, allow (1) local users to obtain portions of kernel data via a TIOCSETD ioctl call to a terminal interface that is being accessed by another thread, or (2) remote attackers to cause a denial of service (panic) by switching from console to PPP line discipline, then quickly sending data that is received during the switch.

Integer overflow in the vc_resize function in the Linux kernel 2.4 and 2.6 before 2.6.10 allows local users to cause a denial of service (kernel crash) via a short new screen value, which leads to a buffer overflow.

Integer overflow in the ip_options_get function in the Linux kernel before 2.6.10 allows local users to cause a denial of service (kernel crash) via a cmsg_len that contains a -1, which leads to a buffer overflow.

Memory leak in the ip_options_get function in the Linux kernel before 2.6.10 allows local users to cause a denial of service (memory consumption) by repeatedly calling the ip_cmsg_send function.

Linux kernel does not properly convert 64-bit file offset pointers to 32 bits, which allows local users to access portions of kernel memory.

The e1000 driver for Linux kernel 2.4.26 and earlier does not properly initialize memory before using it, which allows local users to read portions of kernel memory. NOTE: this issue was originally incorrectly reported as a "buffer overflow" by some sources.

Integer overflow in the hpsb_alloc_packet function (incorrectly reported as alloc_hpsb_packet) in IEEE 1394 (Firewire) driver 2.4 and 2.6 allows local users to cause a denial of service (crash) and possibly execute arbitrary code via the functions (1) raw1394_write, (2) state_connected, (3) handle_remote_request, or (4) hpsb_make_writebpacket.

cryptoloop on Linux kernel 2.6.x, when used on certain file systems with a block size 1024 or greater, has certain "IV computation" weaknesses that allow watermarked files to be detected without decryption.

The Vicam USB driver in Linux before 2.4.25 does not use the copy_from_user function when copying data from userspace to kernel space, which crosses security boundaries and allows local users to cause a denial of service.

Buffer overflow in the ixj telephony card driver in Linux before 2.4.20 has unknown impact and attack vectors.

Stack-based buffer overflow in the ncp_lookup function for ncpfs in Linux kernel 2.4.x allows local users to gain privileges.

The do_mremap function for the mremap system call in Linux 2.2 to 2.2.25, 2.4 to 2.4.24, and 2.6 to 2.6.2, does not properly check the return value from the do_munmap function when the maximum number of VMA descriptors is exceeded, which allows local users to gain root privileges, a different vulnerability than CAN-2003-0985.

The mremap system call (do_mremap) in Linux kernel 2.4.x before 2.4.21, and possibly other versions before 2.4.24, does not properly perform bounds checks, which allows local users to cause a denial of service and possibly gain privileges by causing a remapping of a virtual memory area (VMA) to create a zero length VMA, a different vulnerability than CAN-2004-0077.

Real time clock (RTC) routines in Linux kernel 2.4.23 and earlier do not properly initialize their structures, which could leak kernel data to user space.

Multiple integer overflows in the 32bit emulation for AMD64 architectures in Linux 2.4 kernel before 2.4.21 allows attackers to cause a denial of service or gain root privileges via unspecified vectors that trigger copy_from_user function calls with improper length arguments.

Various routines for the ppc64 architecture on Linux kernel 2.6 prior to 2.6.2 and 2.4 prior to 2.4.24 do not use the copy_from_user function when copying data from userspace to kernelspace, which crosses security boundaries and allows local users to cause a denial of service.

Integer signedness error in the Linux Socket Filter implementation (filter.c) in Linux 2.4.3-pre3 to 2.4.22-pre10 allows attackers to cause a denial of service (crash).
